As the world considers redefining the precise length of a second, Singapore’s Centre for Quantum Technologies has delivered a new contender for the ultimate master timekeeper.Conti...
Initial results from the world’s first two working nuclear clocks indicate that China’s timepiece is about six times as stable as the one in Vienna, according to papers published t...
Author(s): Matteo RiniTwo independent teams have built operating nuclear clocks—devices that might one day rival the best atomic clocks and offer new ways to probe fundamental phys...
By measuring the squishing and unsquishing of thorium-229 nuclei, two teams created a new type of clock that could someday beat the precision of atomic clocks.
A self-stabilizing nuclear clock has achieved precision equivalent to roughly one second in 30 million years, though it still trails the best optical atomic clocks. For a clock tha...
A small Singaporean research team has beaten scientists in China and the United States to build the world’s most accurate atomic clock. The clock, built with a single ion of a rare...
A thorium-229 nuclear clock uses feedback from atomic nuclei to correct laser-frequency drift, operating for more than 24 hours with frequency instability approaching one part in a...

New timekeeping tools could revolutionize studies of fundamental physics The post Nuclear clocks finally see the light appeared first on Physics World.
Drawing less than 120 mW and tolerating 30 krad of total ionizing dose, the chip-scale atomic clock keeps LEO satellites synchronized when GNSS timing is unavailable.
Две независимые группы исследователей в Вене и Пекине одновременно создали первые ядерные часы, которые отсчитывают время по «сжатию и разжатию» атомных ядер тория, тяжёлого радиоа...

For more than 50 years, a group of timekeepers has been quietly sneaking extra seconds onto the world's clocks.
Today, we’re surrounded by technologies we could justifiably describe as time thieves. In ancient Greece, those who wanted to know where their time was going consulted a device the...
I guess everyone just uses their phone for the time these days… “Dear PoPville, I’m wondering if anyone knows what’s up with the USNO Master Clock at the observatory on […]
Каждая секунда на вашем смартфоне зависит от огромной системы, которая должна работать с почти немыслимой точностью. Сегодня Россия играет в ней неожиданно важную роль, а технологи...
Earth’s rotation subtly changes the length of the day. Now our clocks won’t change with it — at least not for a very long time.
